The great horned owl is one of the most commonly seen owls; it lives an average of 13 years in the wild or 38 years in captivity. There are over 170 individual owl species, and each one has a separate lifespan.
Owls are nocturnal predators, and they actively hunt starting at dusk and continue through the late night hours. They are carnivores and eat mice and other small animals. Since owls do not have teeth to tear off the flesh of their prey, they eat their prey in whole and regurgitate small pellets of indigestible matter, such as bone, feathers and fur.
